Figure 27.—A freshly dead sei whale from the Pacific ([top]) and a stranded specimen in an advanced stage of decomposition at Cape Island, S.C. ([bottom] and [inset]). Note that even though the distinctive coloration of the fresh specimen has faded on the rotting specimen, the numbers and lengths of the ventral grooves (38 to 56 in number and stopping well short of the navel) still permit the specimen to be distinguished from fin, blue, and Bryde's whales, in all of which the grooves extend at least to the navel.
